Arsenal skipper Cesc Fabregas is confident that he can manage the leg injury which has hampered him in recent weeks.
The 23-year-old believes that he has not suffered a recurrence of a hamstring problem, but that fluid around the same area is the cause of his discomfort.
He told the club's official matchday programme:"The good news is there is no tear on the hamstring, nothing. It's just a little bit of fluid, but it keeps coming back.
"It's outside the muscle, the 'skin' of the muscle. It's not really a muscle injury, it's fluid that keeps coming back and it's very annoying.
"We are working on it, looking at my hips because they are always very tight.
"We have to work on it ,but also understand that I am 23 years old and I've played many, many games.
"Soon I will play my 200th Premier League game, as well as nearly 60 for the national team and 60 in the Champions League.
"So that's a lot of games for my age and I have to take care of myself."
